items produced 3. In the past the average proportion of by a certain process has been 3 per cent and this is a satisfactory quality level. If samples of size thirty are taken at regular intervals, set up an attributes control scheme.

How many observations are in the data set? How do I calculate this in the "R" program?

In sampling situations, the population consists of:   Select one: a. specific values like level of education. b. all cases that conform to a designated set of specifications. c. the entire physical world over a finite period of time. d. partial data utilized in characterizing the whole.

For this project you have to do the following: 1) list five different things that are normally distributed. Examples that you can't use since I came up with them: Shoe size, middle finger length, oxygen level, electricity bill, wait times on line to pay at target. You must give the website where you found that they are normal for each one of them. 2) measure yourself and use the normal distribution to find out what percent of the population is less than use. What this means is that for one of the five things in 1) you need to make sure that you can find the mean and standard deviation. So an example would be: I found the oxygen level mean and standard deviation to be 98.3 and 1.1. My oxygen level is 98.9. Using the normal distribution calculator I found that 69.3% of the population has a lower measure of that.

9a. For binomially distributed data set, approximately what proportion would be below the mean and also within one standard deviation? 16.5%,25%,33%,50%,66%

Determine the minimum sample size required when you want to be 95% confident that the sample mean is within one unit of the population mean and o=17.2. Assume the population is normally distributed
